Abstract
The aim of this paper is a critical investigation of some correction factor
s in the quantum-efficiency calibration of photodetectors, in the photon-co
unting regime, by means of correlated photons generated through a parametri
c down-conversion process inside a non-linear crystal. An analysis is given
of the main correction factors found in a real experimental situation, wit
h different techniques for performing coincidence counts.
